ICMP Echo packets or Ping packets send data to a (given) server which then replies with the exact packet (data) in return. In essence this program bounces your data back and fourth between a (given) server and your computer instead of storing it on a drive or on someone else's drive it. So your data is living on the internet, in the internet's delay between you and the remote server. This can be unsafe data storage if the link between you and the remote server ever dropped.
